A Guide to Test The Performance of Different Desiccants


Are you getting the moisture protection you pay for? Today, it’s difficult to answer that question. The reason is the current lack of a common standard to test the performance of different desiccants. This is problematic because it makes it impossible to accurately compare the various desiccants available on the market.

With this guide, you will get a clear view of why this is an issue, and what you can do in order to make sure you get what you pay for.

The more moisture, the better result

An example of the importance of similar conditions during testing is the amount of moisture available in the test. If there is a lot of moisture available inside a container or a climate chamber during testing, the result will be higher absorption than if there was less moisture available.

This is true regardless of the type of desiccant tested – be it calcium chloride, silica gel, clay, or desiccants from different brands. Some manufacturers claim their product’s absorption rate is 500% and beyond. That’s fantastic, but is it comparable to real conditions?

Make an informed choice

This mix-up in numbers can lead to decisions based on incomplete test data. The consequences may be severe if the desiccants you choose don’t perform accordingly when it matters. If you are in the process of choosing a new desiccant supplier, we hope this article will help you choose the optimal solution for your needs.
